The internal ventilation of the ball mill affects the grinding efficiency

Ball mill internal ventilation is good or bad, a direct impact on the efficiency of grinding play, which open grinding and take the natural pull wind mill more common problems. Ventilation on the one hand, the mill can be discharged within the fine powder, so as not to affect the grinding efficiency; the other hand, can reduce the grinding temperature, to avoid gypsum dehydration tail ball paste ball blocking grate. When the moisture content of the material is too large and the mill is not well ventilated, the water vapor in the mill is difficult to discharge, and not only the wet fine powder adheres to the blockage of the grate but also the material throughput and flow rate per unit time. At the same time, these abrasive grinding materials due to static electricity will be lining the working surface attached to the formation of "buffer layer", resulting in abrasive impact on the material crushing function greatly reduced. When the liner surface stick

The internal ventilation of the ball mill affects the grinding efficiency

With the thickness of 1mm, the large-scale ceramic ball mill manufacturers can reduce the impact force of the abrasive body to one-third of the material without material, which leads to the decrease of mill output and grinding power consumption. More simple solution to the upper part of the axial exhaust fan cylinder, while the mill rotary screen, the material chute and other parts of the closed plugging to prevent air leakage caused by ventilation short-circuit. This mill ventilation within the smooth, but also completely solve the grinding head to take ash problem. Similarly, the wind lock system must also do a good job, otherwise, fan wind directly from the discharge outlet was taken away, forming a ventilation short circuit, the mill is not much wind. Now many factory unloading mouth add flap valve, the actual effect is not ideal, must re-make the lock wind device.
Ball mill grinding process can be divided into two kinds, open flow and ring flow, or open or closed circuit. Ball mill in all the same conditions, the ring flow is closed-circuit production than open-circuit production is to open the way to increase production by 20% to 35%, and ring flow of products obtained by more uniform particle distribution, excessive grinding of the situation less. Ball mill is a very important factor in the efficiency of particle processing of abrasive materials, this matter is too large particle size of the ball mill grinding energy use, and even down to 2%. In order to improve the efficiency of ball mill ball mill cylinder liner is an important protection tool to avoid abrasive materials on the cylinder and a direct impulse to form an attack, and ball grinding chamber also has regular trajectory movement adjustment function status to help the grinding position better Sports, ball mill, thereby enhancing the grinding efficiency and productivity of ball mill.
